I have installed XCTU software on an Ubuntu 16.04 box; It fires up OK but the application freezes when I either ask for Adding a Module or Discovering Radio Module. It shows modal window saying: Operation in progress… and never moves forward from this point on; I cannot close this window nor the main XCTU window and the only way I manage to do that is killing the java process.
The linux user I use is already included in dialout group. Also dmesg shows the module being detected and attached to /dev/ttyUSB0.
Any idea what I could to to make it work?
